Chocolate & Hazlenut Loaf Cake

I decided to see if I convert the recipe for the Orange and Fig cake (below):

I swapped the ground almonds for ground hazlenuts
I swapped the fruit juice and zest for hazlenut syrup (Monin coffee syrup) and vanilla extract
I swapped the extra virgin olive oil for hazlenut oil
I added a cup of copped hazlenuts (toasted) and chocolate chunks
I topped with chocolate sauce made by microwaving 50g dark chocolate, 120g milk chocolate, 50g unsalted butter and 1 tbsp of golden syrup for 1 minute
I poured the sauce over the cakes (made two again) and added a few whole toasted hazlenuts
